Seems that lots of students don't like word problems. I believe it has to do with their lack of experience with them. You have to parse the words, extract the data, make some sense about how to arrange the data, create an equation or equations of some kind, and then solve the darn thing. Seems like a "work" problem to me.
Ok, so here goes.
Let w = speed of the wind
Let 4w + 30 = speed of the plane in still air
Distance = rate X time
Time is constant. Time = Distance / rate
Let D1 = 240 (distance traveled against wind)
Let D2 = 360 (distance traveled with wind)
Let r1 = (4w+30)-w (rate against the wind)
Let r2 = (4w+30)+w (rate with the wind)
Solve for w (speed of wind)
Solve for 4w + 30 (speed of plane in still air)
